Meta opens Horizon Worlds SDK 2.0 with multi-user physics and persistent scenes

Gaming · 6 min read

Horizon Worlds SDK 2.0 introduces deterministic multi-user physics so objects behave consistently across participants, reducing desyncs in collaborative experiences. The physics engine supports server-authoritative objects while allowing local prediction for responsiveness.

Persistent scene anchors let creators pin content to real-world coordinates and share them across sessions, enabling persistent installations and location-based social features. The SDK also improved asset streaming and memory management for large worlds.

Meta included new tools for moderation and user reporting in-world, plus analytics hooks to measure engagement with persistent objects. The company provided guides on optimizing physics-driven interactions for comfort and performance in VR.
